Molar Teeth
_Designed by TurnRock ( http://www.thingiverse.com/thing:33643 )
_The molars or molar teeth are the most posterior and most complicated kind of tooth in most mammals. In many mammals they grind food during chewing; hence the Latin name mola, "millstone". Molars show a great deal of diversity in size and shape across mammal groups.
_In humans, the molars are four- or five-cusped teeth. Adult humans have twelve molars, in four groups of three at the back of the mouth. The third, rearmost molar in each group is called a wisdom tooth. It is the last tooth to appear, breaking through the front of the gum at about the age of twenty, although this varies from individual to individual. Ethnicity can also have an impact on the age at which this occurs, with statistical variations between groups.In some cases, it may not even erupt at all.
The human mouth contains upper (maxillary) and lower (mandibular) molars. They are: maxillary first molar, maxillary second molar, maxillary third molar, mandibular first molar, mandibular second molar, and mandibular third molar.
